Motion of a domain wall (DW) in weak ferromagnets induced by a high-frequency field that is not small is investigated. The nonlinear regime of DW oscillations, in which the maximum velocity of the wall can reach the limiting velocity, is realized experimentally. The proposed theory describes this motion and determines the parameters of the nonlinear DW motion from the data obtained experimentally.
